BRONANDER, on MONTCLAIR, NEW JERSEY FIRE'EXTINGUISHER AND SUPPORT THEREFOR Applicationv filed October 10, 1927. Serial No. 225,060.

This invention relates to fire extinguishers and supports therefor.

the type of extinguisher having a fire extinguishing liquid sealed therein such, for instance, as carbon tetrachloride.

The invention has for its salient object to provide an extinguisher and support there-.

for so constructed and arranged that the ex-v tinguisher is easily accessible and can be readily and quickly utilized to extinguish a fire.

Another object of the invention is to providean extinguisher so constructed and ar-, ranged that the extinguishing fluid will be automatically released in case of fire.

Another object of the invention is to providea frangible extinguisher and support so constructed and arranged that the extinguisher will be protected from accidental breakage but can be easily and quickly broken to rel ease the fire extinguishing fluid-therein in case of fire.

Another object of the invention is to provide an extinguisher support that is simple, practical and inexpensive in construction and so constructed and arranged that the extinguisher can be easily inserted therein and removed therefrom. 7

Further objects of the invention willappear from the following specification taken in connection with the drawing, which forms a part of this application, and in which Fig. 1 is a longitudinal sectional eleva-.

I tion of an extinguisher andsupport confrangible material, and containing a fire'ex- V tinguishing fluid such as carbon tetrachlo- The invention relates more particularly to,

ride, and means for supporting the container in such a way that it can be easily and quickly pulled away from its support and broken to releasethe fire extinguishing fluid. The frangible container is preferably substantially enclosed within a shield or casing so constructed that it can be opened up and a new container can be placed there-: in after one container has been used. The. casing has a hammer having a portion extending therethrough and a blow on the hammer will cause the frangible container to break, thus liberating the fire extinguishing fluid contained thereby. The hammer may, if desired, be spring actuated and be held under tension by the spring and in spaced relation to the container by a fusible member.

The casing or shield is held on a bracket or supporting member by means of resilient elements carried by the bracket or support and adaptedto engage the casing. Theresilient means coact with the casing in such away that the casing can be easily removed from the bracketor support.

Further details of the invention will appear from the following description.

In the particular form ofthe invention illustrated the extinguisher is supported on a bracket consisting of an elongated plate 10 having its lower end 11. extending laterally to a position beneath a hammer hereinafter described. The upper, end of the plate is folded back to form a lip 12.

Ifdesired, the bracket can be supported by the loop formed at the junction of the lip 12 and the main body portion of the bracket 10. For instance, the lip may be placed over the bottom edge of a pocket in the door of an automobile. In order, however, to facilitate the, attachment'of the bracket to a vertical wall, counter-sunk open-i ings. l4 and 1 5 are formed in the body portion of the bracket and in the lip 12. An opening 16 is also formed in the bracket in. alinement with the countersunk opening 14 to permit the passage of a screw through the opening 14. i

ion

ing comprising a central portion and end' portions 26 and 27. ,The central portion 25 consists of a band or sleeve having outturned flanges 30 and 31 tapered with respect to each other. The band has a plurality oflips 32 'a-t the lower end which secure to the band the ibotto'm dome shaped portion 27 ofthe casing, f these lips being, so located that'the two free edges of'the band can be bent outwardly to a sufficient extent 'to permit the frangible container to be withdrawn from the casing.

The band is also formed with similar lips 35 atthe upper end thereof for securing there'tothe upper. portion 26 of the 'casing which partially surrounds the container and extends around substantially one-half, or the front'half of the upper end thereof. After a container has been placed within the casing the casing'is secured thereto by a clamping plat'e'36having flanges 37 and 38 formed on 1a taper and adapted to extend around the flanges 30 and 31 of the central portion 25 offthe casing. f

The casing and containe'ris s'ecured'to the bracket by means of resilient legs 40 and 41 offaU-shaped spring 42. The spring is se- "curedtothe front faoe'of the bracket 10 by 46"formed on thefian'ges and extending into engagement with the spring. The upper ends of the'legs 40 and 41 can slide beneath .the lugs 46 topermitthe legs which are bowed" means of flanges 42 and 43 and lugs 45 and *inwardly'tobe forced outwardly. In order to mountrthe casing and container on the bracket the casing is positioned as shown in I Figaiwith the legs 40 and 41 engaging between the outer surface of'the band or centraiportion' 25 of the casing andthe flanges G37 and'3'8 of the clamping plate 36. This can "be accomplished by forcing one of the legs" laterally and snapping the other leg into the position shown in Fig. 4or, by moving the container downwardly so that thetapered olamping plate will be positioned with its flanges behind the spring legs 40 and 41.

"In order to facilitate breaking thefrangiible container a hammer having a head 48 land aos'hank 49is slidably mounted in a bushing 50 carried bythe bottom portion 27 of the container. Int'he form of the invention shown in Figs. 1 to 3 inclusive the hammer jis'normalljy pressed by a spring 52 against the depressed portion 21 of the lower end of 'tlie container. The portion 11of the bracket extends beneath the lower end ofthe hammer shank 49 and prevents accidental engage= ment therewith.

In order to use the device shown in Fig. 2 the container is removed from the bracket by sliding it upwardly or merely by grasping it firmly and pulling it away from the bracket andthen the shank 49 of the hammer is engaged against any suitable object and forced inwardly, breaking the lower end of the frangible container. The bottom 27 of the casing has a plurality of perforations or openings .55 to permit the fire extinguishing fluid to pass ther-ethrough. V

In the forino flie-invention shown in Fig. 5 the hammer is normally held in retracted position spaced from the depressed portion 21 of the container by means'of a pin 56 which extends through the hammer shank 49 and beneath the lower end of the bushing 50. The pin '56 is preferably formed of fusible-metal so that in case of fire the pin will melt, thereby permitting the spring 52 to force the hammer upwardly into engagement with the container, causing the container to be broken and the fire extinguishing fluid to be released. The'pin 56 may, if desired,have'a' cord 57 secured thereto and extendingin a position in which it will be accessible so that the pin can be manually withdrawn, thus releasing the hammer.

As above stated, in order to use the extinguisher it is merely necessary'to grasp the casing and remove it from the bracket, where upon the hammer can be forced inwardly to break the container and the fluid can be sprinkled 'or poured on the fire. Also, as stated, with the device shown in Fig. 5,-in case of fire the pin 46 will melt, thus autogiati'cally releasing the fire extinguishing uid. After a container has been broken and the fluidhas been emptied a new container can be easily and readily inserted in the casing in the manner herelnabove described.
